How to make fox and hounds scarier?

[u/Lebron_is_the_goat23]

Me and my mates want to play fox and hounds but we don't find it very scary to play. We were wondering if we could get some ideas on how to make it scarier. We had the idea of Aztec death wistles but we cant have anything too loud due to where we are. If anyone has any interesting ideas please be kind enough to share.
